Answer:
See below
Step-by-step explanation:
The solution choices all agree that x = 1±√2. The second equation tells you ...
y = ±2√(x+2)
so the sign of the √2 term in x is the same as the sign of the √2 term in y. The answer choices circled in red are the ones that meet this requirement.
The charge should be $6. I believe I set this up correctly; let me know if there are any errors. Hope this is helpful & accurate.
#21 is 95 degrees
#22 is B
When y=3/x translated right 3 units , we get y = 3/(x-3).
Then we translate y = 3/(x-3) , 3 units up and get y = 3/(x-3) +3.
So the answer is B.
y=3/(x-3) + 3
